I've been trying to upgrade the memory in my Pavilion XL844. It came with 64Mb originally, and I increased it to 192 years ago. Now I want to throw in another 256 but am having problems. I have the same type - 100/133 Mhz SDRAM, and HP says that matching is not required.
The first attempt gave me all sorts of weird lockups and freezes - I thought I had a virus until it occurred to me it was probably bad memory. Viola, removing the chip stopped the lockups. I exchanged the chip for another, and am now getting blue screens flash and the system continuously reboots. I caught the following error: IRQL not less than or equal to. Any ideas?
